Today, network operators are forced to converge their networks in order to reduce Operational Expenses (OPEX), and also to eliminate unnecessary additional Capital Expenditures (CAPEX) on multiple parallel networks. Every network operator is attempting to solve the convergence problem of providing the greatest number of services on the least amount of infrastructure. In order to drive faster returns on investments, traditional telecom carriers are trying to integrate residential broadband services, advanced enterprise data connectivity services and video into existing voice networks; cable operators are trying to add VoIP and commercial services to video and cable modem services. At the same time, there is a massive migration from traditional SONET/SDH- and PDH-based TDM services to IP/Ethernet-based services, including Voice, Video, Internet Access and Layer-2 Business Services.
